Atomic scale visualization of topological spin textures in the chiral magnet MnGe
Jacob Repicky, Po-Kuan Wu, Tao Liu +8
Spin polarized scanning tunneling microscopy is used to directly image topological magnetic textures in thin films of MnGe, and to correlate the magnetism with structure probed at…
Changes of Magnetism in a Magnetic Insulator due to Proximity to a Topological Insulator
Tao Liu, James Kally, Timothy Pillsbury +9
This letter reports the modification of magnetism in a magnetic insulator Y3Fe5O12 thin film by topological surface states (TSS) in an adjacent topological insulator Bi2Se3 thin fi…
Non-Hermitian coherent coupling of nanomagnets by exchange spin waves
Hanchen Wang, Jilei Chen, Tao Yu +16
Non-Hermitian physics has recently attracted much attention in optics and photonics. Less explored is non-Hermitian magnonics that provides opportunities to take advantage of the i…
Magnetic Properties and Electronic Structure of Magnetic Topological Insulator MnBiSe
Tiancong Zhu, Alexander J. Bishop, Tong Zhou +12
The intrinsic magnetic topological insulators MnBiX (X = Se, Te) are promising candidates in realizing various novel topological states related to symmetry breaking by magn…
Chiral spin-wave velocities induced by all-garnet interfacial Dzyaloshinskii-Moriya interaction in ultrathin yttrium iron garnet films
Hanchen Wang, Jilei Chen, Tao Liu +14
Spin waves can probe the Dzyaloshinskii-Moriya interaction (DMI) which gives rise to topological spin textures, such as skyrmions. However, the DMI has not yet been reported in ytt…
